The development and simulation demonstrations of a dual T shaped Planar Inverted F Antenna (PIFA) are presented in this paper. The design of single feed dual T PIFA operating at 500MHz to 3GHz is presented. CADFEKO version 5.5 is used in dual T shaped PIFA antenna. A prototype of the antenna was constructed and the results exhibit a proper operation of the antenna in terms of return loss, bandwidth, efficiency and gain. The antennas feature remarkable properties while occupying a significantly small space, which makes them strong candidates for mobile applications and for the wireless communication applications too.
